@@ -50,7 +50,7 @@ There are two pins, `DFU` and `FRST` that bootloader will check upon reset/power
- `Double Reset` Reset twice within 500 ms will enter DFU with UF2 and CDC support (only works with nRF52840)
- `DFU = LOW` and `FRST = HIGH`: Enter bootloader with UF2 and CDC support
- `DFU = LOW` and `FRST = LOW`: Enter bootloader with OTA, to upgrade with a mobile application such as Nordic nrfConnect/Toolbox
- `DFU = HIGH` and `FRST = LOW`: Factory Reset mode: erase firmware application and its data
- <s>`DFU = HIGH` and `FRST = LOW`: Factory Reset mode: erase firmware application and its data</s>
- `DFU = HIGH` and `FRST = HIGH`: Go to application code if it is present, otherwise enter DFU with UF2
- The `GPREGRET` register can also be set to force the bootloader can enter any of above modes (plus a CDC-only mode for Arduino).
`GPREGRET` is set by the application before performing a soft reset.
